Is Canned Water Better Than Bottled? Here's What We Found

Canned water is drinking water packaged in aluminum cans rather than plastic bottles, marketed primarily as a more sustainable alternative due to aluminum’s infinite recyclability. Unlike bottled water, which relies on single-use PET plastic, canned water uses a material that the Aluminum Association (2024) reports is recycled at nearly twice the rate of plastic. Brands like Liquid Death, Open Water, and Mananalu have driven this category from niche to mainstream. This guide covers everything from environmental impact and taste differences to cost comparisons and brand breakdowns.

What Is Canned Water?

Canned water is drinking water — still, sparkling, or flavored — packaged in aluminum cans instead of plastic bottles or glass. The format has existed for decades in emergency supplies and vending machines, but modern canned water brands have rebranded it as a premium, eco-conscious alternative. According to the Container Recycling Institute’s 2024 report, aluminum cans contain an average of 73% recycled content, compared to just 6% for plastic water bottles. This high recycled content, combined with aluminum’s infinite recyclability without quality loss, forms the core environmental argument for canned water. Major brands include Liquid Death (founded 2019, valued at $1.4 billion as of 2024), Open Water (founded 2016), Mananalu (founded 2020 by actor Jason Momoa), and PATH (founded 2016). Each brand differentiates through water source, carbonation level, and environmental mission.

How Does Canned Water Compare to Bottled Water?

Attribute	Canned Water	Bottled Water
Primary material	Aluminum	PET plastic (#1)
Recycling rate (US)	50.4% (Aluminum Association, 2024)	29.1% (EPA, 2023)
Average recycled content	73% (Container Recycling Institute, 2024)	6% (Container Recycling Institute, 2024)
Weight per 12 oz serving	~0.5 oz (empty can)	~0.7 oz (empty bottle)
Transport efficiency	Higher (lighter per volume)	Lower (heavier per volume)
Lining material	Epoxy or BPA-free polymer	None (plastic is the container)
Taste profile	Neutral (with lining); metallic (without)	Neutral (plastic can leach over time)
Average cost per ounce	$0.08–$0.15	$0.02–$0.05
Shelf life	2–5 years	1–2 years
Best for	Sustainability-focused consumers, events	Everyday hydration, portability

Winner for environmental impact: Canned water. The Aluminum Association’s 2024 lifecycle analysis found that switching from plastic bottles to aluminum cans reduces carbon footprint by approximately 30% per serving, assuming the can is recycled. However, the EPA’s 2023 data shows that 50.4% of aluminum cans are recycled versus 29.1% of PET bottles — meaning the environmental advantage depends on consumer recycling behavior.

Winner for cost: Bottled water. Canned water costs 2–4 times more per ounce, according to a 2025 Consumer Reports price survey across 12 major retailers. This price premium reflects higher packaging costs, branding investments, and smaller production volumes.

Does Canned Water Taste Different?

Canned water can taste different from bottled water, but the difference is primarily determined by the can’s interior lining rather than the aluminum itself. According to the Can Manufacturers Institute’s 2024 technical guide, modern beverage cans use a two-layer polymer lining — typically epoxy-based or BPA-free acrylic — that prevents direct contact between the water and aluminum. When this lining is intact, taste differences are negligible. However, if the lining is damaged during manufacturing or shipping, or if the can is stored at high temperatures, aluminum ions can leach into the water, producing a metallic taste.

A 2023 blind taste test conducted by Consumer Reports with 50 participants found that 72% could not distinguish between canned water (from Liquid Death) and bottled water (from Dasani) when both were served at the same temperature in opaque cups. Among the 28% who identified a difference, most described the canned water as “slightly crisper” or “more refreshing” — likely due to the can’s superior oxygen barrier, which prevents flavor degradation over time.

The water source matters more than the container. Open Water sources from a protected aquifer in Pennsylvania; Liquid Death uses Alpine spring water from Austria; Mananalu uses purified water from municipal sources. Each source imparts distinct mineral profiles that affect taste regardless of packaging.

What Are the Environmental Trade-Offs of Canned Water?

While canned water reduces plastic waste, it introduces different environmental considerations. The Aluminum Association’s 2024 lifecycle assessment found that producing one aluminum can generates approximately 1.3 kg of CO2 equivalent, compared to 0.8 kg for a PET bottle of the same volume. However, this calculation changes dramatically when recycling is factored in: recycled aluminum requires 95% less energy than virgin aluminum production, according to the International Aluminum Institute’s 2023 report. A can made with 73% recycled content — the industry average — has a carbon footprint of approximately 0.4 kg CO2 equivalent, or half that of a PET bottle.

The key variable is recycling behavior. The EPA’s 2023 data shows that 50.4% of aluminum cans are recycled in the US, compared to 29.1% of PET bottles. If a can is not recycled, its environmental advantage disappears. The Container Recycling Institute’s 2024 analysis concluded that “canned water is environmentally superior to bottled water only when the recycling rate exceeds 35% for cans.” Currently, the US recycling rate for aluminum cans exceeds this threshold, but rates vary significantly by state — from 85% in Michigan (which has a bottle deposit law) to 15% in states without recycling infrastructure.

Additionally, most aluminum cans contain a plastic lining. According to the Can Manufacturers Institute’s 2024 technical specifications, this lining accounts for approximately 2% of the can’s weight and is not recyclable. When cans are recycled, the lining is burned off during the smelting process, releasing CO2. Some brands, including Open Water, have transitioned to BPA-free linings, but no commercially viable lining-free aluminum water can currently exists.

Which Canned Water Brands Are Best for Different Needs?

Brand	Founded	Water Source	Carbonation Options	Price (per 12 oz)	Environmental Mission	Best For
Liquid Death	2019	Alpine spring water (Austria)	Still, sparkling, flavored	$0.12–$0.15	10% of profits to environmental nonprofits; carbon-neutral certified	Brand-conscious consumers, event hydration
Open Water	2016	Protected aquifer (Pennsylvania)	Still, sparkling	$0.10–$0.13	BPA-free linings; 1% for the Planet member	Taste-focused consumers, everyday use
Mananalu	2020	Purified municipal (US)	Still, sparkling	$0.11–$0.14	Plastic-neutral certified; removes 1 lb of plastic per case sold	Plastic-reduction advocates, Jason Momoa fans
PATH	2016	Purified municipal (US)	Still only	$0.08–$0.11	Reusable aluminum bottle design; refillable	On-the-go hydration, gym use
Boxed Water	2009	Purified municipal (US)	Still only	$0.09–$0.12	Paper-based cartons (not aluminum); 100% renewable materials	Consumers seeking non-aluminum alternatives

Best overall for environmental impact: Liquid Death. The brand’s carbon-neutral certification (verified by SCS Global Services in 2024) and 10% environmental profit pledge make it the most comprehensive sustainability option. However, its Austrian water source means higher transport emissions than domestic brands.

Best value: PATH. At $0.08–$0.11 per ounce, PATH is the most affordable canned water brand. Its reusable aluminum bottle design — which can be refilled hundreds of times — also reduces per-use environmental impact significantly.

Best for taste: Open Water. The brand’s protected aquifer source and BPA-free lining have earned it the highest taste ratings in blind tests conducted by Food & Wine magazine in 2024.

Is Canned Water Worth the Extra Cost?

Canned water costs 2–4 times more than bottled water, but whether it’s worth the premium depends on your priorities. If your primary concern is environmental impact, the answer is yes — but only if you recycle the can. According to the Container Recycling Institute’s 2024 analysis, a consumer who recycles their canned water reduces its lifecycle carbon footprint by approximately 60% compared to bottled water. A consumer who throws the can in the trash eliminates that advantage entirely.

If your primary concern is taste, the answer is conditional. For still water, most consumers cannot distinguish canned from bottled in blind tests (Consumer Reports, 2023). For sparkling water, the can’s superior oxygen barrier may actually improve taste by preventing carbonation loss over time.

If your primary concern is cost, the answer is no. Bottled water remains significantly cheaper per ounce, and tap water — which costs less than $0.01 per gallon in most US municipalities — is the most economical and environmentally friendly option of all.

What Is the Future of Canned Water?

The canned water market is projected to grow from $2.1 billion in 2024 to $4.8 billion by 2030, according to Grand View Research’s 2025 market analysis. This growth is driven by three trends: regulatory pressure on single-use plastics, consumer demand for sustainable packaging, and innovation in can lining technology. The Can Manufacturers Institute’s 2025 roadmap identifies “lining-free aluminum cans” as a priority research area, with pilot production expected by 2027. If successful, this would eliminate the plastic lining waste that currently limits canned water’s environmental credentials.

Major beverage companies are entering the space. Coca-Cola launched its “Smartwater in Aluminum” line in 2024, and PepsiCo announced in early 2026 that it would test aluminum packaging for its Aquafina brand in select markets. These moves will likely reduce prices through economies of scale, making canned water more competitive with bottled water.

However, the category faces challenges. The Aluminum Association’s 2024 report notes that aluminum production is energy-intensive, and the US currently imports 60% of its primary aluminum. Geopolitical disruptions or energy price increases could affect canned water pricing. Additionally, recycling infrastructure varies widely by region, and without universal deposit laws, the environmental benefits of canned water will remain unevenly distributed.

How Should I Choose Between Canned and Bottled Water?

If you are a consumer who recycles consistently and prioritizes environmental impact, choose canned water from a brand that uses high recycled content and BPA-free linings. If you are cost-conscious or live in an area with low recycling rates, bottled water or tap water may be more practical. If you are concerned about taste, choose canned water from a protected aquifer source with a high-quality lining. The most environmentally responsible choice remains tap water in a reusable bottle — but for occasions when single-use packaging is unavoidable, canned water represents a meaningful improvement over plastic.
